GeForce GTX 1660 Ti vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which has core clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

GeForce GTX 1660 Ti		120 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 13% quicker than the Radeon RX 6600 XT in general, because of its greater bandwidth. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 6600 XT should be much (more or less 75%) faster with regards to anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 107904 (75%)

Pixel Rate

The Radeon RX 6600 XT should be much (approximately 75%) better at AA than the GeForce GTX 1660 Ti, and also able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 53952 (75%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
